Processing methods | The compounded product should be dried to <400ppm before injection molding. Precautions should be taken to avoid moisture absorption of the dried granulate during processing, for example while sitting in the hopper of the injection molding machine. In general, injection molding conditions should be selected to avoid high stresses and high (back) pressures on the material in order to limit length reduction of the glass fibers. It is recommended to select an injection molding machine with a low ratio of barrel volume / show weight to avoid degradation in the barrel. A barrel volume of maximum 5 times the shot weight is recommended. The achievable cycle time for automatic operation depends on a number of machine, mold and product properties. As the product needs time to crystallize into full stereocomplex PLA, the crystallization time in the mold typically at 120°C is the rate limiting step. Although automatic operation will also run using lower mold cooling temperatures, this is not recommended because this will result in products with reduced thermal and dimensional stability. Typical settings, may require optimization: |
